Scrape batter into the prepared pan. Bake 1 hour 15 minutes to 1 hour 25 minutes, or until a toothpick comes out clean. Cool in pan 15 minutes, then invert onto a rack to cool completely.
Make the caramel icing —
Melt butter in a saucepan over medium heat. Stir in brown sugar and cook 2 minutes until dissolved. Slowly whisk in evaporated milk; bring to a gentle boil, then simmer 3–4 minutes. Remove from heat and cool slightly. Beat in powdered sugar and vanilla until smooth and spreadable.
Frost and finish —
Spread icing over the fully cooled cake, working quickly as it sets. Create decorative swirls with a spoon or spatula.
Troubleshooting & Consistency Tips
Dense cake: Cream butter, shortening, and sugar until pale and airy; measure flour by weight or fluff-scoop-level to avoid packing.
Sticking to the pan: Grease and flour thoroughly, getting into every ridge. Let the cake rest 15 minutes before turning out.
Icing too thin: Beat in more sifted powdered sugar, 1–2 tablespoons at a time; or let it cool a few minutes to thicken.
Icing too thick or setting fast: Whisk in a teaspoon or two of warm evaporated milk to loosen.
Sugary icing texture: Cook brown sugar until fully dissolved and glossy before adding milk; sift powdered sugar to prevent lumps.
Storage & Make-Ahead
Room temperature: Keep covered up to 3 days.
Refrigerate: Up to 6 days; bring slices to room temp for best texture.
Freeze: Wrap unfrosted cake tightly up to 2 months; thaw and frost with fresh caramel icing.
Make-ahead icing: Can be made 1 day ahead; rewarm gently and whisk before spreading.
Why This Recipe Works
A traditional pound cake method—thorough creaming, room-temperature ingredients, and a low 325°F bake—builds a fine, even crumb that stays moist. Shortening adds structure while butter contributes flavor. The caramel icing starts with fully dissolved brown sugar so it sets silky, not gritty; a touch of evaporated milk gives body and a clean dairy finish that complements the buttery cake.Cake recipes
Expert Tips
Use room-temperature butter, shortening, eggs, and milk for an emulsion that won’t curdle.
Scrape the bowl often—unmixed butter pockets cause tunnels and uneven rise.
For ultra-neat swirls, apply a thin crumb coat of icing, chill 10 minutes, then finish with thicker swoops.
Try a pinch of kosher salt in the icing to sharpen the caramel notes.
Bake in a light-colored pan; dark pans brown faster—start checking at 70 minutes.
